Buying Guide
Power Output
Start by matching the generator’s wattage to the appliances and systems you want to support. Larger homes and broader backup goals generally call for higher output, while smaller backup needs may be covered by more modest units.
Fuel Type
Fuel flexibility can make a big difference during outages. Tri-fuel models offer the most options, dual-fuel models still provide helpful versatility, and standby units usually focus on a more permanent home setup.
Portable vs. Standby
Portable generators are generally easier to move and often cost less, while standby generators are designed for permanent installation and more seamless home backup operation. The best choice depends on your budget and how automated you want the system to be.
Starting Method
Remote electric start and electric start can make a generator much easier to use during an outage. If convenience matters, this is a feature worth prioritizing.
Transfer Switch Readiness
Many home backup buyers should look for transfer switch ready models. This helps simplify integration with your home’s electrical system and can make backup use more practical.
Safety and Monitoring
Features like CO Alert or a CO sensor add another layer of awareness during operation. For home use, safety-focused features are an important part of the decision.
